Lenses / Re: Using two Canon EF 1.4X entenders
« on: February 15, 2013, 12:14:12 PM »
As mentioned earlier you cannot stack two Canon 1.4x extenders. I have recently stacked the following: Canon 1DX + Canon 500mm F4L version I + Canon 2x II + Canon 1.4x II. This shot was at ISO 5000, 1/400, +2 EV at effective 1400mm on tripod. Full overcast about an hour from sunset. The camera showed F8 and 1000mm. Auto-focus did work with center point focus.
I'm adding the photo to this post. Not an award winning capture. I was just trying it out to see what it would do with branches, low light, etc. This is about a 60% crop into the photo.
